How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
What the label discloses
The listing-image panel publishes 6 separately quantified rows and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin C (as ascorbic acid) | 1000 mg | — | |
| Vitamin D (as cholecalciferol) | 125 mcg | — | |
| Zinc (zinc citrate, zinc gluconate, and zinc picolinate) | 50 mg | — | |
| Clean Q-Defend™ Immune Proprietary Blend | 350 mg | — | |
| Turmeric (Curcuma longa) (Root) Powder, Bifidobacterium lactis, Bromelain, Echinacea Purpurea (Echinacea purpurea) (Aerial Parts) Extract (4:1), Garlic (Allium sativum L.) (Bulb) Powder, Ginger (Zingiber officinale) (Root) Powder, Irish Moss (Chondrus crispus) (Whole Herb) Powder, L-Lysine Hydrochloride, Nettle (Urtica dioica) (Leaf) Powder, Reishi Mushroom (Ganoderma lucidum) (Fruiting Body) Extract (4:1), Rose Hips (Rosa canina) (Fruit) Powder, Sweet Wormwood (Artemisia annua) (Leaf) Powder | — | — | |
| Elderberry (Sambucus nigra) (Fruit) Extract (10:1) | 100 mg | — | |
| Sophora Japonica (Sophora japonica) (Flower bud) Extract (10:1) (Quercetin) | 100 mg | — | |
| Black Pepper (Piper nigrum) (Fruit) Extract (4:1) | 5 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Ingredient amounts are hidden inside a blend
The panel lists “Clean Q-Defend™ Immune Proprietary Blend” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Registered in NIH's supplement label database (DSLD)
Label #316109 “Immune Defend” (Clean Nutraceuticals), entered 2024-07-25, with the full Supplement Facts on file — see the panel below. Company on file: Manufacturer — Clean Nutraceuticals.
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
Research context is available for the listed ingredients
Published sources describe how turmeric / curcumin, zinc have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH NCCIH — Turmeric, PubMed search: curcumin bioavailability piperine.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,043 on 2026-01-25 to 1,108 on 2026-07-08 (net +65). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…BY RESEARCH Supports immune health* NON-GMO THIRD PARTY TESTED USA MADE GMP CERTIFIED 3RD PARTY TESTED” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Manufacturing claim “…health* NON-GMO THIRD PARTY TESTED USA MADE GMP CERTIFIED 3RD PARTY TESTED” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Benefit claim “…ysine Stinging Nettle Reishi Mushroom Immune Support 60 Capsules Q DEFEND QUERCETIN SUPPLEMENT: Q…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| turmeric / curcumin | Studies typically use 500 mg–2 g. This product’s amount could not be read from public sources, so no comparison is possible. | |
| Zinc (zinc citrate, zinc gluconate, and zinc | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 50 mg — above the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
Documented cautions
- zinc — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
Verifiability profile — 3 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.

Related research & consistency
turmeric / curcumin — NIH NCCIH — Turmeric · PubMed search: curcumin bioavailability piperine · WebMD: turmeric · ClinicalTrials.gov — 286 registered studies
ℹ Use pattern in research: plain curcumin absorbs poorly — most positive trials pair it with piperine (black pepper) or a bioavailability-enhanced form.
zinc — NIH ODS — Zinc fact sheet · PubMed search: zinc supplementation trial · ClinicalTrials.gov — 1,598 registered studies
ℹ Use pattern in research: daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice.
